目的:探讨紫苏叶注射液对犬动脉搭桥术后血液流变学参数的影响.方法:将20只试验犬随机分为高、中、低剂量组(1 434 mg/kg,478 mg/kg,159 mg/kg)及对照组,采用同侧自体颈外静脉重建颈总动脉,术后头静脉滴注紫苏叶注射液,持续给药3周,分别于给药前、给药后第1周、第2周和第3周测定血液流变学各项参数.结果:与用药前比较,低、中、高剂量紫苏叶注射液均能显著或极显著降低低切(10 s-1)时全血黏度、全血还原黏度、红细胞聚集指数和红细胞电泳指数(P<0.05,P<0.01);高剂量紫苏叶注射液能显著降低中切(60 s-1)时全血黏度、全血还原黏度(P<0.05),但低剂量和中剂量紫苏叶注射液对中切(60 s-1)时全血黏度、全血还原黏度无显著影响(P>0.05);低、中、高剂量紫苏叶注射液对高切(150 s-1)时全血黏度、全血还原黏度、红细胞变形指数、红细胞刚性指数、血浆黏度和红细胞压积无显著影响.结论:紫苏叶注射液能明显改善搭桥术后犬的血液流变学参数,降低血液黏度. 相似文献

紫苏叶注射液的制备(英文) 总被引:1,自引:0,他引:1
[Objective] To extract the effective component rosmarinic acid from Folium perillae,study preparation technology and quality control of rosmarinic acid injection and provide test basis for hemorheological drug development and clinic application.[Method]The coarse powder of Folium perillae(40 μm)was lixiviated with hot water and acidized to make aqueous extracts.Rosmarinic acid from the aqueous mixture was extracted with Ethyl Acetate.And Et Ac was evaporated to obtain primary product.The injection was purified by pH adjustment.Concentration of rosmarinic acid in the injection was detected by high performance liquid chromatography(HPLC).Contents of tannin,resin and oxalate were eliminated according to the Chinese Pharmacopeia(2005 edition).Stability,irritation,haemolyticus,LD50 and thermogenic substance of this injection were also detected.[Result]The content of rosmarinic acid in Folium perillae injection is 2.81 mg/ml,and the content of LD50 was 406.82 mg/kg.This injection was consistent with the stipulation of Chinese Pharmacopeia(2005 edition).[Conclusion]The preparation technology of this experiment was reasonable.The stable qualities of the prepared injection meet the injection requirement. 相似文献
